Well, I thought I attached the image. I’ll try again with it pasted in.

I have found the Crossley ID Guide for Raptors to be a great resource. The format is too big to be considered a field guide, but I like to compare photos taken in the field with the photos in the book. 

I’ve attached a poorly scanned image from the spread on Bald Eagles in flight — adult, subadult, and immature.
